Introduction
This Manual is a guide to using the EvalAg6130 evaluation board fitted with a
Silvertel Ag6130 Single Channel Power Sourcing Equipment (PSE) Module.
This board is designed to assist with evaluating the use of Silvertel’s Ag6130
in an application; as such it has been designed to pass through
10/100/1000BASE-T Ethernet data signals from any source connected to J100 onto
the powered device connected to J101
Input
4.1 Power
The EvalAg6130 evaluation board is powered using a DC Power supply. The
positive supply is connected to binding post J1 and 0V to binding post J2
using 4mm Banana connectors, bare wire, or fork connectors.
The supply should be between 50V and 57V for normal operation. if the Ag6130
is set to Type 1 Mode the Supply can be as low as 45V

4.2 Data
A data source can be connected to the RJ45 Data port J100. This data will be
transposed onto the Data and Power output port J101 via the data transformer.
The data traces on the evaluation board have been designed to pass through
10/100/1000BASE-T Ethernet data signals. No processing or amplification of
this signal will be performed on the evaluation board
Power option select
The Ag6130 has an option to select its output power and class. These can be chosen by placing a jumper on the appropriate pins of LK7. If the power option is changed while a device is being powered by Ag6130, the change will not occur until after the powered device has been powered down and the detection cycle has been performed.

Pairset Select
The EvalAg6130 contains four links LK1-4 that connect the cable pairs to the
output of the Ag6130. In order to enable power transfer down a given pairset
jumpers should be inserted onto the relevant links or removed if power is not
desired down the given pairs.
Pairsets 1-2 and 4-5 are connected to the positive output of the Ag6130. While
pairsets 36 and 7-8 are connected to the negative output of the Ag6130. In
high power modes all four jumpers should be fitted.
When only two pairs are to be connected, in order to guarantee compliant
operation either pairs 1-2 & 3-6 should be connected, or pairs 4-5 & 7-8
should be connected.
Operation
To ensure that the Ag6130 does not apply power to a non-PoE enabled device the output port first checks for a valid PoE signature. If the Ag6130 does not see a valid signature then it will disconnect, wait approximately 2 seconds then try again. Once a valid signature has been detected the Ag6130 will then perform classification to determine the power requirement of the PD, only after this has occurred will the Ag6130 supply power to the powered device.
Status Output
The Status LED will illuminate if the Ag6130 is providing power to the output port. It will also flash as per the table below when an error has occurred. If this functionality is not desired, it can be disabled by removing the jumper on link LK5.
| Fault Condition | Status Pulses (200ms) |
|---|---|
| Device Identification Error | 1 x Logic 1 Pulse |
| Input Voltage < UVLO limit | 2 x Logic 1 Pulses |
| Short Circuit | 3 x Logic 1 Pulses |
| Overload Current | 4 or 5 x Logic 1 Pulses |

Test Setup
Figure 2 shows the basic set up using the EvalAg6130 evaluation board powered by a DC power supply with an output between 50V and 57V. The powered device and data source need not be connected before power is applied.
The equipment required: –
➢ Power supply unit, +44-57V output e.g. 60V bench power supply
➢ Powered device
➢ CAT5e/CAT6a cables
Optional equipment: –
➢ Data source e.g. PC
